After that.......it should be powered on when you turn the key on.
For our setup, we turned them on at 5000 rpm (50 on the box) and off at 5000rpm (which means they are on at 5000 and off below 5000).
This resulted in more power above 5000rpms.

I noticed a slight delay in the "ON" time. If you wanted to be picky, I would change it to on at 49 and off at 49 so that it would turn on at about 5000rpms.
